Answer:
B = 155° , C = 25° , D = 155°
Step-by-step explanation:
Given
A = 25°
C = A = 25° [ Vertically Opposite angles ]
Now
A + B = 180°( being linear pair)
25° + B = 180°
B = 180° - 25°
B = 155°
Also
D = B = 155°( vertically opposite angles )
Answer:
$102.876
Step-by-step explanation:
multiply 85.73 by 120% bc there is the price of the meal and 20% of the original price
30 should be the correct answer
Let's say this number is a:
a*(a-9) = 90
a^2-9a-90 = 0
(a-15)(a+6) = 0
a = 15 or a = -6
Therefor a. would be the correct answer :)
